Answer:
B. Base pairing occurs within an RNA molecule to give RNA the three-dimensional shape needed for specific functions.
Explanation:
Ribonucleic acid, known as RNA, is a type of nucleic acid found in living systems. In opposition to the other type of nucleic acid (DNA), RNA is a short single stranded molecule. Both DNA and RNA are made of nucleotides, composed of a phosphate group, nitrogenous bases and a pentose sugar.
The presence of ribose sugar and Uracil base in RNA instead of deoxyribose sugar and thymine base respectively structurally differentiates the molecule from DNA. However, base pairing occurs within the RNA molecule to form the three-dimensional shape of the RNA, which is key to the specificity of its function.

Explanation:
A scientific question is an answerable and testable question that explains a particular aspect to a more general inquiry about nature. It is written in a manner that addresses a scientific inquiry. A scientific question has the following characteristics;
1. It is specific: A scientific question is not broad or cumbersome such that other questions are attached to it. It rather seeks the answer to a particular aspect of a broader question.
2. It is testable and replicable: This implies that to answer the question, standard scientific measures can be employed to solve it. It should also be replicable in any standard laboratory in the world using the equipment and measures specified.
3. It should be objective: This implies that the question should not be subject to personal opinions or have moral undertones to it.
4. It should solve a problem: Our world is posed with so many problems. A scientific question should provide answers to a specific part of one of these questions.
5. It is a new question that has not been satisfactorily answered before: A scientific question should not have received generally accepted scientific answers. It addresses a new problem that has not been answered previously.
